Using Sensors command for Lua to use in generating rings - bash

Question

I am trying to reverse engineer a conky/lua script to tailor fit my machine. The thing is, hwmon does not pickup the correct value. I resorted in using sensors to detect CPU temperature. I was able to successfully use it in lua to create an if/then/else function that changes colour depending on the temperature however, I could not get it to work with the "ring"
This is what I have currently:
local cpu_temp = io.popen("sensors -u | awk '/temp1_input:/ {print $2; exit}'"):read("*l")
local cpu0_temp = tonumber(cpu_temp:read('*a'))
settings_table = {
{
--1
name='hwmon',
arg='cpu0_temp',
max=110,
bg_colour=0x3b3b3b,
bg_alpha=0.8,
fg_colour=0x165cc4,
fg_alpha=0.8,
x=185, y=125,
radius=120,
thickness=4,
start_angle=0,
end_angle=240
},
}
function temp_watch()
warn_value=60
crit_value=80
local file= io.popen("sensors -u | awk '/temp1_input:/ {print $2; exit}'")
local temperature = tonumber(file:read('*a'))
if temperature<warn_value then
settings_table[1]['fg_colour']=normal
elseif temperature<crit_value then
settings_table[1]['fg_colour']=warn
else
settings_table[1]['fg_colour']=crit
end
file:close()
end
function conky_main()
temp_watch()
end
I am no expert in lua and I was patterning the first 2 lines on what I have learned and from this Question
What I get is this error:
conky: get_sysfs_info(): read from failed
conky: can't open '': No such file or directory
The original settings table looks like this:
settings_table = {
{
--1
name='hwmon',
arg='1 temp 1',
max=110,
bg_colour=0x3b3b3b,
bg_alpha=0.8,
fg_colour=0x165cc4,
fg_alpha=0.8,
x=185, y=125,
radius=120,
thickness=4,
start_angle=0,
end_angle=240
},
And it is stuck to 50 degrees Celsius.
